- Avoid deformation of the intemal bolts,

- Avoid overstressing of intemal push bolts,

- The seal gasket, confined into the diaphragm, follows the relative movement of the

diaphragm with respect to the channel due to differential thermal expansion, thus guaranteeing

the sealing even during transient conditions.
